The only remaining question respecting Ocean Penny Postage is the statesmanlike and proper one, _How is the expense to be paid?_ In the first place, the government would not be required to pay any more money for the transportation of its mails than they pay now. This great boon can be given to the people without a dollar’s additional cost. Our own experience under the postage act of 1845, proves this. While the number of letters is doubled, the whole expense of the post-office is diminished—especially that part which might most naturally be expected to increase, that is, the transportation of the mails. The freight of a barrel of flour, weighing 200 pounds, is about fifty cents. Of course, the equitable price of ten thousand letters added to any given mail, which would not weigh so much as a barrel of flour, would make no assignable difference in the cost upon a single letter. As both sailing ships and steam packets are becoming multiplied, individual competition may now be relied on to keep the price of transportation of mails from ever rising above its present standard. The increase of the number of letters makes but very little addition to the aggregate expense of the post-office. In the first year of the penny postage in England, there were ninety-three millions of letters added to the mails, and only £70,231 to the whole expenditure of the department, including the cost of introducing the new system, with all its apparatus. This amounts to 0.181_d._; less than two-tenths of a penny each for the added letters. In 1844, there were 21,000,000 letters added to the circulation, and not a farthing added to the cost. These letters yielded about £90,000 in postage, every penny of which went as net gain into the treasury. I have no means of stating how much of the £450,000 added to the yearly expenditure of the British Post-office, is chargeable to the great increase of facilities and accommodations, both of the public and of the department; but have understood that by far the greater part of it arises from this, and not properly from the mere increase of letters. It may be safely assumed that, for any number of letters now added to the mails in Great Britain, the additional expense will not exceed half a farthing each letter, and the rest will be clear profit to the post-office. As the plan of Ocean Penny Postage includes also the inland postage prepaid in each country, it follows that each country would realize from three-quarters to seven-eighths of a penny advantage on every letter added to the present ocean mails.
